Twelve month analysis of atmospheric normals based on representative site coordinates
The Heipker See climate profile provides a systematic look at long-term atmospheric patterns using 1991 to 2020 NASA POWER data. These metrics track average minimum and maximum temperatures, daily precipitation rates, relative humidity, wind speed, and daylight hours throughout the calendar year at a single representative coordinate. The records offer a baseline for understanding the annual rhythm of this nature reserve, excluding transient weather events or short-term forecasts.

Long-term thermal movement and average daily precipitation across all twelve calendar months
Compare long-term temperature bounds, average daily precipitation, humidity, wind, and calculated daylight across the calendar year.

See two months side by side and how much they differ. Both use the same 1991–2020 climate normals and NASA POWER data point as the table above, so they show typical conditions, not a forecast.
